Finland lifts nuclear weapons ban in historic vote, deepening NATO integration

Jun 17, 2026

Finland's parliament voted 125-61 to lift a decades-old ban on nuclear weapons, a historic shift to deepen its integration with NATO. The move, which repeals a 1987 law, allows for the transport and possession of nuclear arms for national defense on its territory. While Finland says it has no plans to host such weapons, Russia has warned the decision leads to an "escalation of tensions" on their shared 830-mile border.
